Hello. Great site. I recently purchased a 04 996 AE with 113K. My OBD showed random misfires. I checked the plugs and coils. Coils were cracked so I replaced all plugs and coils. The plug condition was consistent across all cylinders... ash gray color and no pitting or carbon or oily plugs. The misfire codes returned and I noticed the idle is rough but the engine pulls and is smooth off idle and through the rev range. I purchase the Durametric and I ran actual values (codes showed random misfires across most cylinders) the check engine light came on at one point but had gone away on it's one while waiting for my cable to arrive. My problem is I have lots of data to look at but no way to understand or to translate it into actionable information. I am not even sure that I captured the right parameters for my misfire error codes. Is there a good place to look at what the actual values should be for a 996? or a link to any tutorials on how to read the data and translate that into a what to check or troubleshoot? Any advice would be greatly appreciated and thoroughly utilized.
